Description

Die Erfindung betrifft eine Energieversorgungseinrichtung für explosionsgeschützte elektronische Funktionseinheiten.The invention relates to a power supply device for explosion-proof electronic functional units.

Derartige Energieversorgungseinrichtung werden in automatisierungstechnischen Anlagen zur Speisung von prozessnahen Komponenten und diesen zugeordneten Kommunikationseinrichtungen eingesetzt.Such energy supply device are used in automation systems for supplying process-related components and associated communication devices.

Aus der EP 1014531 A2 ist eine derartige Energieversorgungseinrichtung bekannt, bei der die Funktionseinheiten aus einer hochfrequenten Wechselspannung gespeist werden, die für jede der Funktionseinheiten individuell über eine Drossel ausgekoppelt wird. Es wird vorgeschlagen, die Wicklungen der Dro5sseln als miteinander verbundene, im Wesentlichen deckungsgleiche Leiterbahnen einer Mehrebenenleiterplatte auszubilden, wie sie prinzipiell aus der JP 62154609 A1 bekannt sind. Darüber hinaus wird vorgeschlagen, die erforderliche Induktivität der Drosseln durch Ferritkerne herbeizuführen, die durch Öffnungen in der Mehrebenenleiterplatte hindurchragen. Bei Auslegung der Drossel mit Feritkern müssen zusätzliche Maßnahmen ergriffen werden, die verhindern, dass der Ferritkern nicht seine Position verändert und/oder bricht. Ein zusätzlicher Luftspalt oder eine Positionsänderung des Kernes verändern die Induktivität der Drossel und können dadurch den Explosionschutz negativ beeinträchtigen.From the EP 1014531 A2 is such a power supply device is known in which the functional units are fed from a high-frequency alternating voltage, which is coupled out for each of the functional units individually via a throttle. It is proposed to form the windings of the Drossels as interconnected, substantially congruent strip conductors of a multi-level printed circuit board, as they are in principle from the JP 62154609 A1 are known. In addition, it is proposed to bring about the required inductance of the reactors by ferrite cores, which project through openings in the multilevel printed circuit board. When designing the choke with ferrite core, additional measures must be taken to prevent the ferrite core from altering and / or breaking its position. An additional air gap or a position change of the core change the inductance of the throttle and can thereby adversely affect the explosion protection.

Dieser Anordnung ist mit mehrere Nachteilen behaftet. Zur Aufnahme der Ferritkerne sind Ausnehmungen in die Mehrebenenleiterplatte einzubringen. Durch die Vielzahl der Ausnehmungen und ihre Bestückung mit jeweils zwei Ferritkernhälften ist der Hestellungsaufwand für die Mehrebenenleiterplatte sehr hoch. Zur Einhaltung der gemäß Explosionschutznorm geforderten Isolationsabsände ist eine Mindestplatinenfläche sowie mehrfache Metalisierungsebenen (Layer) für die Drosseln erforderlich. Weiterhin ist zum Erreichen der erforderlichen Induktivität der Drosseln eine Mehrebenenleiterplatte mit mindestens sechs Metallisierungsebenen erforderlich, während für die restliche Verdrahtung vier Metallisierungsebenen genügen. Schließlich begrenzt die Fläche der Drosseln innerhalb der Mehrebenenleiterplatte die Anzahl der anschaltbaren Funktionseinheiten.This arrangement has several disadvantages. To accommodate the ferrite cores recesses in the multi-level PCB are to be introduced. Due to the large number of recesses and their placement with two ferrite core halves of Hestellungsaufwand for the multi-level PCB is very high. To comply with the isolation limits required by the explosion protection standard, a minimum board area and multiple metalization levels (layers) are required for the reactors. Furthermore, to achieve the required inductance of the chokes, a multilevel printed circuit board having at least six levels of metallization is required, while four levels of metallization are sufficient for the remainder of the wiring. Finally, the area of the chokes within the multilevel printed circuit board limits the number of connectable functional units.

Der Erfindung liegt daher die Aufgabe zugrunde, die Nachteile des Standes der Technik zu überwinden und eine wechselspannungsspeisende Energieversorgungseinrichtung für explosionsgeschützte elektronische Funktionseinheiten anzugeben, die mit geringem Aufwand eine Vielzahl von Funktionseinheiten speisen kann.The invention is therefore based on the object to overcome the disadvantages of the prior art and to provide an AC voltage supplying power supply device for explosion-proof electronic functional units that can feed a variety of functional units with little effort.

Erfindungsgemäß wird diese Aufgabe mit den Mitteln des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den rückbezogenen Ansprüchen angegeben.According to the invention this object is achieved by the means of claim 1. Advantageous developments of the invention are specified in the dependent claims.

Die Erfindung geht aus von einer Energieversorgungseinrichtung für explosionsgeschützte elektronische Funktionseinheiten, bei der die Funktionseinheiten aus einer hochfrequenten Wechselspannung gespeist werden, die für jede der Funktionseinheiten individuell über eine Drossel ausgekoppelt wird.The invention relates to a power supply device for explosion-proof electronic functional units, in which the functional units are fed from a high-frequency alternating voltage, which is individually coupled for each of the functional units via a throttle.

Erfindungsgemäß sind die Drosseln als miteinander verbundene, im Wesentlichen deckungsgleiche Leiterbahnen einer Mehrebenenleiterplatte ausgebildet und auf einer Verteilungsleiterplatte stehend angeordnet, wobei die Anzahl der Metallisierungsebenen der Mehrebenenleiterplatte größer ist als die Anzahl der Metallisierungsebenen der Verteilungsleiterplatte.According to the invention, the chokes are formed as interconnected, substantially congruent strip conductors of a multilevel printed circuit board and arranged standing on a distribution board, wherein the number of metallization levels of the multilevel printed circuit board is greater than the number of metallization levels of the distribution board.

Durch die auf der Verteilungsleiterplatte stehende Anordnung der Drosseln ist deren Platzbedarf auf der Verteilungsleiterplatte viel geringer, so dass eine größere Anzahl Drosseln auf derselben Fläche der Verteilungsleiterplatte untergebracht werden. Dementsprechend mehr Funktionseinheiten sind bei gleichen Dimensionen an die Verteilungsleiterplatte anschaltbar.By standing on the distribution board arrangement of the chokes their space requirement on the distribution board is much lower, so that a larger number Chokes are housed on the same surface of the distribution board. Accordingly, more functional units can be connected to the distribution board with the same dimensions.

Vorteilhafterweise kommt die Verteilungsleiterplatte mit einer geringen Anzahl von Metallisierungsebenen aus, so dass der Gesamtaufwand aus Verteilungsleiterplatte und zugehörigen Drosseln geringer ist als bei Unterbringung der Drosseln in der Verteilungsleiterplatte. Darüber hinaus liegen die Drosseln vor dem Einbau als separat prüfbare Einheiten vor.Advantageously, the distribution board comes with a small number of levels of metallization, so that the total cost of distribution board and associated chokes is less than when the chokes are accommodated in the distribution board. In addition, the chokes are pre-installed as separately testable units.

Durch die vertikale Anordung der Drosseln ist es technologisch einfach die Drosseln durch Verguss fest miteinander zuverbinden und damit den Explosionschutzforderungen zugenügen.The vertical arrangement of the chokes, it is technologically easy to connect the chokes by potting firmly together and thus meet the explosion protection requirements.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels näher erläutert. In der einzigen Figur ist eine Energieversorgungseinrichtung für explosionsgeschützte elektronische Funktionseinheiten dargestellt, bei der die Funktionseinheiten aus einer hochfrequenten Wechselspannung gespeist werden, die für jede der Funktionseinheiten individuell über eine Drossel 1 ausgekoppelt wird. Im Einzelnen ist eine Verteilungsleiterplatte 4 mit einer Mehrzahl von Drosseln 1 vorgesehen, wobei die Drosseln 1 stehend auf der Verteilungsleiterplatte 4 angeordnet sind.The invention will be explained in more detail below with reference to an embodiment. In the single figure, a power supply device for explosion-proof electronic functional units is shown, in which the functional units are fed from a high-frequency alternating voltage, which is individually coupled for each of the functional units via a throttle 1 . Specifically, a distribution board 4 having a plurality of chokes 1 is provided, with the chokes 1 standing on the distribution board 4 .

Die Drosseln 1 sind als miteinander verbundene, im Wesentlichen deckungsgleiche Leiterbahnen 2 einer Mehrebenenleiterplatte 3 ausgebildet. Dabei weist jede Metallisierungsebene der Mehrebenenleiterplatte 3 zumindest eine Windung der Drossel 1 auf. Zur Ausbildung der erforderlichen Windungszahl sind in der gezeigten Ausführungsform beispielsweise sechs Metallisierungsebenen mit Leiterbahnen 2 erforderlich.The chokes 1 are formed as interconnected, substantially congruent strip conductors 2 of a multi-level printed circuit board 3 . In this case, each metallization level of the multilevel printed circuit board 3 has at least one turn of the throttle 1 . To form the required number of turns, for example, six metallization levels with printed conductors 2 are required in the illustrated embodiment.

Die Drosseln 1 sind auf der Verteilungsleiterplatte 4 mechanisch befestigt und elektrisch kontaktiert. Dazu weist die Verteilungsleiterplatte 4 mehrere Ebenen von Leiterbahnen 2 auf. Der Bedarf an Metallisierungsebenen der Verteilungsleiterplatte 4 ist jedoch geringer als bei der Mehrebenenleiterplatte 3. Zur Ausbildung der erforderlichen Leiterbahnen 2 sind in der gezeigten Ausführungsform beispielsweise nur vier Metallisierungsebenen mit Leiterbahnen 2 erforderlich.The chokes 1 are mechanically fixed and electrically contacted on the distribution board 4 . For this purpose, the distribution board 4 on several levels of conductors 2 . However, the need for metallization levels of the distribution board 4 is lower than in the multi-level circuit board 3. To form the required traces 2 , for example, only four levels of metallization with traces 2 are required in the embodiment shown.
